Abstract

PURPOSE:To prevent the color displacement of a copy, by supporting inner circumferential end parts of a drum with bearing bodies and holding inner circumferential both end parts of the drum with said bearing bodies to each other. CONSTITUTION:To one holding plate 28 for a copying drum 11 three bearing bodies 31 are mounted. This bearing body is constituted by a pair of cones 32, bearings 33 provided in its inside, bearing 34 provided between the both cones 32 and a supporting shaft 35 for supporting these bearings and the like. Then tapered faces 32a of the both cones 32 are contacted to sloped parts 25c1, 25c2 of a gear ring 25 respectively. Subsequently, if both end sides in an inner circumferential part of the drum are held between the left side cone 32 of the pair of the cones 32 and a cone 37, the copying drum 11, gear ring 25 and ring 27 are formed as an integral unit. In this way, the copying drum can axially absorb its looseness not to cause axial deflection, thus the color displacement of a copy can be prevented.
